“The most distinctive human achievements have been reached by exceptional teams.

Collective Confidence is your guide to higher levels of performance for your team, and you will think differently about your possibilities and potential.

“At a moment when teams are fractured, trust is eroding, and uncertainty feels relentless, Collective Confidence is an existential balm. It’s a book that will transform the way you think about what makes teams great. Unlike so many voices in the space, André’s wisdom is both earned and rigorous. This book is the bridge between where your team is today and what it could become.” 

 

– Simone Stolzoff, bestselling author of How to Not Know and The Good Enough Job

“One of the best ways to build a new team is to give them a hard, important goal and have them work through it together. Real work, real stakes. When the team achieves a shared win, the confidence that follows is contagious. People start treating each other differently. They speak up more. They trust more. There is a kind of camaraderie you cannot fake. I have seen this happen many times, but I did not have a name for it until André Martin called it collective confidence. This book gives leaders a practical way to understand it, and more importantly, to build it.”
